"we believe that our world consist of all that we can see, unaware of the fact that there may be entire universes right above our noses. Although another universe might be hovering just above us floating in the fourth dimension, it would appear to be invisible".(Parallel worlds , ch -seven ; by - Michio Kaku, ISBN 0-385-50986-3).

`There more things in heaven and earth than are dreamt of in your philosophy `- Shakespeare.

More than 100 years ago a realised spiritual giant ,Swami Vivekananda told (see Complete Works of...) -~ `just this moment so many other universes or beings are passing through us. We do not see them ,neither they do see us`.
The amusing fact is that we ,human-beings with our so limited perceptual powers and a little intelligence ,think that everything that is there or anywhere ,are within our tight grip!
